The 32-year-old Big Bang Theorystar wore a studded white mini dress as she celebrated her engagement to professional equestrian Karl Cook with a party that was straight up oozing in pink.

The festivities included belting out early 2000s hits – like "Hollaback Girl," "I'm a Slave 4 U," and "Crazy in Love" — and an epic dance party where the bride-to-be absolutely destroyed it on the floor.

Oh, and celebrity stylist Brad Goreski was right there with her, tearing it up.

"The most magical night ever," the actress wrote on Instagram after the event. "Thank you to my amazing friends and family for celebrating my future as Mrs. Cook! I have never felt more loved."

While Kaley's not spilling the date and location of her impending nuptials, if her hen party has revealed anything, it's that her big day will definitely be an affair to remember ... with lots of pink.
